interesting trick with extrudes and pillars

[azizg]

I just found an interesting trick, in case I'm not the last to know about it, I thought I'd write a description.

if you draw a square and extrude it you get an extruded square. Obviously. But if you draw a smaller square inside it and then extrude them together you get a hollow extrude.

You don't have to draw the two squares then use the 'trim' command and then extrude the resulting polyline. this save one job in the task, and means the cut out shape is still easily modifyable.

Brilliant.

That is handy, thanks azizg.

It looks that way in wireframe but when rendered it's two extrudes. In the OIP it shows "Extrude", when I ungroup it it shows as "2 Extrudes".

The co-extrudes show in wireframe. But go to OpenGl and it is a single extrude?

So for me I do not see the hollow part of your trick.

Clip small from large ... then extrude ; )

Sorry It did work exactly as I described it above. And I still have the object I made in a drawing. However I can't replicate the drawings. I don't know what I did to make it work the first time.

Just one of those odd things.
